Abstract: 258,881. TÚcalÚmit, Ltd., (Assignees of Soc. Anon. des Etablissements TÚcalÚmit). Sept. 22, 1925, [Convention date]. Void [Published under Sect. 91 of the Acts]. Pumps with two or more barrels in series; relief devices.-A lubricat.ing system for a motorvehicle chassis comprises a pump supplying lubricant at low pressure to a branched conduit system, means being provided adjacent the part to be lubricated for discharging the lubricant thereto at increased pressure and in regulated quantities. The pump 6, Fig. 2 draws lubricant from a reservoir 1 past a non-return valve 4 and discharges it past a non return valve 8 into the conduit 22. The piston comprises cup-leathers 10 held between the parts 9. 9<1> of a rod, the lower part 9<1> being formed as a valve to close a passage 5<a> between the valves 4, R when the piston is at the bottom of its stroke. The discharge pressure is controlled hv a spring-pressed relief valve 15 interposed between conduits 19, 21 connected to the conduit 22 and the reservoir respectively. A pressure gauge 20 is connected to the conduit 19. The valve 15 is formed on a rod 14 to the end of which is pivoted a lever 12, one end of which engages a ramp 17. In the inoperative position shown, the lever is in engagement with the top of the ramp and with a knob 11 on the rod 9, thereby holding the valve 15 open and maintaining the piston at the bottom of its stroke. To free the pump, the lever 12 is turned about the axis of the rod 14 so that it moves off the top of the ramp and disengages the knob 11, allowing the valve 15 to close. The reservoir and pump are arranged on the dashboard of the vehicle. Each pressure intensifier comprises a cylinder 26, Fig. 3, connected to a branch 25 from the conduit system and screwed to a member 32 which is secured to the part to be lubricated by a member 33 passing through the member 32. The high-pressure piston 28 of a differential piston is slidable in a passage 32<1> in the member 32, while the low pressure piston, which is slidable in the cylinder 26, comprises a cupleather 27 held between a collar 28<1> on the piston 28 and a member 29 screwed thereon. The members 28, 29 are hollow and in communication with the conduit 25 through a passage 29<2> fitted with a non return-valve 30. The member 33 is provided with a passage 33<1> communicating with the passage 32<1>, a spring-pressed valve 34 being fitted at the outlet from the passage 33<1>. In operation, lubricant supplied by the pump at low pressure first fills the passages 32<1>, 33<1> and the chambers in the members 28, 29 and then moves the differential piston against the action of a spring 37, whereby lubricant is discharged at increased pressure past the valve 34, the valve 30 being closed during this operation. The amount of lubricant discharged is determined by the stroke of the differential piston. When the lever 12 is returned to the inoperative position, thereby causing the valve 15 to open, the spring 37 returns the differential piston to its original position.

Fig. 1 shows ten 2-diode gates P1p, P2p...P10p fed from respective combinations of the leads connected to a2, b2 ... e2 and corresponding 3 - diode gates P1s, P2s ... P10s fed from the complementary combinations of the leads connected to a1, b1...e1. To check for the absence of a positive potential in 2 out of 5 inputs, these inputs are applied to a2, b2 ... e2 to control the gates P1p, P2p ... P10p directly and the gates P1s, P2s ... P10s via transistors TA . . . TE and the leads connected to al, b1 ... e1. If the input is correct, the cathode of one of ten diodes D1s ... D10s does not receive a positive potential via either of the two corresponding gates (e.g. P1p, P1s for D1s) and so conducts to make an output transistor TS conduct to supply a positive signal at S. If the input is not correct, all diodes D1s ... D10s conduct weakly or not at all, and TS does not conduct. To check for the presence of a positive potential in 2 out of 5 inputs, these inputs are applied to a1 ... el, and a plug-in member is changed or reversed or a multi-contact relay is operated to connect points X11 ... X15 to Y21 ... Y25 respectively and points Y11 ... Y15 to X21 ... X25 respectively (instead of the X-Y connections shown), the circuit then operating as in the parent.

Title: Improvements in or relating to the manufacture of sheet materials faced with a flexible synthetic non-inflammable rubber substitute
Inventor: JEPSON MICHAEL DENIS
IPC: B32B27/00
Filed: 1955-08-20
Abstract: 806,009. Binding edges. SPOONER DRYER & ENGINEERING CO. Ltd. Aug. 16, 1956 [Aug. 20, 1955], No. 24054/55 Class 42 (1). Apparatus for applying a strip 5 to the edge of a sheet of material 2 comprises means for guiding the strip at an angle to the edge, means for pressing the strip against the edge, a nozzle 17 for blowing a gas into the bight between the edge and the strip, and means for establishing movement of the sheet relatively to the nozzle and the pressing means. The material 2 may be conveyer belting formed of multi-ply woven fabric faced and impregnated with a flexible synthetic non-inflammable substance such as neoprene or polyvinyl chloride which is also used for the strip 5. Side outlets on the nozzle 17 blow the gas, which is heated, on to the edge of the material 2 and on to the inner face of the strip 5 which are thus softened in readiness for welding by a spring-loaded roller 8. Strips 5 may be simultaneously applied to both edges of the sheet 2 by duplicating the apparatus while the sheet may be tensioned by brake rolls before it reaches the apparatus. The strip 5 which may be thickened at the edges on the side intended for fusion with the material 2, may pass between a pair of spring-loaded tensioning rollers formed to the cross-sectional shape of the strip and over a feed roll before reaching the roll 8. Upper and lower flanges spring-loaded and slidably mounted or arranged for relative screwed adjustment may be provided on the roll 8 which may be cooled by water or by air blown through a circular series of axial apertures. The spindle of the roll may be mounted in spherical self-aligning bearings and where two rolls are used they may be carried with the strip-feeding mechanism by crossslides adjustable towards and away from each other by a hand controlled screw. Alternatively, the slides may be urged towards each other resiliently or by weights. Feed rollers for the material 2 may be arranged to swing the nozzle 17 about a horizontal axis to an inoperative position in which the gas is directed into an exhaust shoot if they cease to rotate.

Title: A slide-rule for use in betting
IPC: G06G1/00
Filed: 1949-09-20
Abstract: 679,924. Calculating-apparatus. HAGEL, H., and HAGEL, C. C. Sept. 20, 1950 [Sept. 20, 1949], No. 24125/49. Class 106 (i). A slide rule for use in racecourse betting in conjunction with a forecast totalizator comprises members movable with respect to one another, one of such members embodying a first logarithmic scale graduated to represent the total units invested on the forecast pool and a second logarithmic scale graduated to represent a proportion of the values of the first scale and another of such members having two oppositely extending logarithmic scales graduated to represent odds and co-operative with said first and second scales. The slide rule is used to determine whether a forecast bet is " advisable " by the comparison of the " chance " involved as calculated from the " odds " against each dog (or horse) being "first." Say, for example, the forecast involves two dogs and the odds, as obtained from a study of the "win" totalizator or from a bookmaker's board, against each of these dogs being " first " are " a " and "b" respectively then the chance of the forecast proving correct is 1/a(b+1). If P represents the total units invested on the forecast pool and "2/3P" is the actual amount paid out then by evaluating the formula 2P/3a(b+1) there is obtained a number representing the total units which would have to be invested on the chosen forecast to give the odds of 1/a(b+1). If the actual amount invested on the forecast pool is greater than this number then the odds obtained would be less than 1/a(b+1), i.e. less than the " chance " involved and such a bet is not considered advisable. The slide rule 1, Fig. 1, is graduated to evaluate the formula 2P/3a(b+1). The logarithmic scale 10 represents "P" the total number of units invested on the forecast pool, the logarithmic scale 11 represents "2/3P," the logarithmic scale 13 on the slide 8 represents the odds " a " and the logarithmic scale 14 represents "(b+1)." This latter scale is obtained by displacing a logarithmic scale representing " b " by 1 unit.
